I did mine Friday night, filed them and they were accepted. Then when looking at my PDF 1040 I noticed my IRA withdrawal was in two spots instead of just one. My fault entirely. I emailed support and got a response three hours later what the issue was and how to correct it. So I set up an amended filing on Saturday. I went through the process four times and could not get past one part where you "finish" the filing. I still had something wrong and could not figure it out. I emailed them again Saturday evening, there was a response in my inbox Sunday at noon. Once again they explained the problem. It still took me three more times through the process to finally finish and be able to file. The last problem was because an "amended" filing I had to go back through everything under a new amended paper.
If I had to, I could file my taxes now in ten minutes after going through all this I understand how it works. But it is different than last year, so it was new to me.
I still prefer to fill out the forms and mail them in, but the postal service is not the same since DeJoy has been there, and I was leery of dealing with Trumps and Elons messing with all the departments.
