Early filers please help

[BeccaD]

Filed 1/27 with TT, accepted same day
No path credits, one dependent HOH filing
Lost bars with “still” processing and amount and tt152 2/15
No movement with transcripts. Still NA with 0.00 and 2/24 with no return filed

Called IRS on Friday. I was told that I was being sent a letter (2/19) and that I would need to fax in what was needed. She said she could not see what was needed and that the “paragraph that was outlined” did not state what was needed. I have insurance through my employer, mortgage interest, property taxes, and my son…whom I do not qualify for the credits. No filing changes since I had him 5 years ago….My SSA account has updated and I am getting no codes on my transcripts, as the say no return filed. I am super confused….
