Based on this, I assume you filed the G-1145 with your petition and received the text from USCIS with your receipt number? With the online account that you can create for the I-129F, there is no way to look at documents related to your case. If you did get the text with the receipt number, and I see they cashed the check, that means they received your case officially and it is in the system. The NOA1s via USPS lately seem to be taking longer than they used to. I've seen comments of 4-6 sometimes even 8 weeks to receive it.
