After you file

It was due to a messy divorce around Covid. I was given half of a return for 2021 so I had no reason to question whether it was filed, I accept responsibility for not inquiring further. I do not know how she filed and have lost track of where she even is at this point. So I intended to file married-separate to rectify the issue. I found out by filling out a fafsa and not having the paperwork then asking the IRS to finish the fafsa, only to find that no return was filed. Another issue is that I can’t acquire the W2s from two places I worked as they went out of business during Covid. I believe I have to fill out a 4506-T to acquire those.
