US Immigration from Russia

Hello!
We have sent a packet with AOS applications (I-485, I-131, I-765) for my wife and daughters via USPS. According to the tracking number last known status:
December 31, 2020
In Transit, Arriving Late
Your package will arrive later than expected, but is still on its way. It is currently in transit to the next facility.
One before that:
December 27, 2020, 11:44 pm
Arrived at USPS Regional Destination Facility
CHICAGO IL DISTRIBUTION CENTER

After an inquiry with USPS they said "it is possible for the item to have been delivered without a scan". I have called USCIS several times asking whether they have received a packet and was told "no", last time today. They are asking to wait for 90 days since the date of supposed delivery because of their backlog.
We don t know whether the package was delivered to the USCIS or was lost by USPS. And we won t potentially know for more than a month.

What should we do now? If we just wait and then figure out the package was truly lost, we are just wasting time now - my wife cannot work (she really wants to start working!), cannot travel outside of the U.S.

Can we assemble and send another AOS package to USCIS? If we do and in case when the first package actually made it through to the USCIS, what will happen if there will be a second set of applications?
USCIS customer service representative also said if the payments from both of the packets will go through, it would be almost impossible to reverse the payment. I wonder if there are other issues with potentially having duplicate applications.
Please advise!

Does the countdown timer to NOA2 start when USCIS processes the application, or does it start on the date you receive your NOA1?

Hello.
It s probably a silly question but did the USCIS get the package?

Someone is supposed to sign it, isn t?

This is the only status it shows

I would like to file a joint tax return with my spouse, who has been going through the adjustment process to obtain a green card. She has arrived in USA as a K1 fiancee, but she could not get any SSN as SS offices were closed due to Covid. Since we are already married, her K1 visa has expired and she cannot get a SSN. I checked the IRS web site and found out that ITIN (individual Tax Identification Number) can be used in place of SSN in the joint return. However, I cannot request a ITIN before we file the joint tax return. I found it very strange. It looks like we need to submit our federal tax return with Form W7 Form (Application for Tax Identification Number) and attach her foreign passport. Can someone confirm that my understanding is correct? I appreciate your help.

PS. Her passport is her only identification document here is USA as we cannot get her a driver's licence without SSN. Has anyone send the original passport to get ITAN and received it back? Note that we cannot get a certified copy of her passport.

Not realizing that her greencard was conditional and would expire in two years, my wife's Greencard expired 3/24/2020.

I am just now realizing I need to now resolve this.

From what I have read, I need to include an explanation with "good cause" to explain the delay.

Are there any suggestions on this?
