US Immigration from Pakistan

We got IL recently, and this is what they mentioned in the letter !
what should we do now? the taxes are still under process by IRS.
we have been dq d in april 2020 and provided 2018 taxes + pay stubs + AOS !

should we upload new AOS now ? Should we upload 2019 tax returns & w2 on ceac ?

will there be an issue of not providing 2019 tax transcript at the time of interview?

I have a few questions. I just read this and I am now confused.

1) I made my cousin my joint-sponsor for my husband but the site says cousins cannot sponsor it. Will it affect my husband s case?

Also, since my cousin is my joint sponsor since my income level isn t a lot; how will the NVC accept an expedite based on financial hardship when they already needed an AOS, to prove that my joint-sponsor is willing to accept legal responsibility for supporting the family member with me...?

2) Then why financial hardship a reason to accept the expedite? Like yes I m struggling financially and I have other medical reasons to expedite the case too; but that s why I needed a joint-sponsor to file (AOS) In first place because I do not earn a lot... so how will they accept the expedite based on the "Financial hardship" reason then?

3) Can I still expedite it after being DQ d?

can anyone explain this in details? Like this is really confusing...

any one knows how much time takes after expedite request accepted to interview date and us visa in hand ???
