I decided to submit a refund request and will be using another service.
It's already been a week since I made my first post here. It's getting so close to 4/15 that if I were to keep waiting for (hopeful) news with no concrete timeline, I would have no time to act on a backup plan to get everything submitted comfortably. Especially considering that the blank 7206 line 1 issue and the rejection errors are two separate (but in theory, related) issues. I hope I get my request approved (I doubt it) but getting my submissions in and moving on is more important to me at this point.
