US Immigration from Romania

We received a "request for evidence" notice in the mail from USCIS with regard to our pending I-485. There was a minor error in the I-864 Affidavit of support and USCIS is requesting a corrected and updated form with our latest financial and tax information. We originally Filled in August of last year with 2017, 2018, and 2019 tax returns and W2s attached. If we update the form to the latest financial and tax documents, that would require 2020 tax returns and W2. Unfortunately we haven't completed our taxes this year because my wife doesn't have and can't get a social security number so in the meantime we are trying to get her a tax ID number so we can complete our taxes. My question is, because we haven't filed yet do we need to send our tax return from 2020 or can we just send the W2 from? I can't get ahold of USCIS to ask them.

Hello. I got my ssn card today and i noticed my middle name is missing 2 letters. The name on my visa is correct. I read they only allow 16 letters and my name is longer than that. Is that a problem? Should i call and try to fix it?
