My e-file was finally accepted this morning. I noticed earlier posts in this thread that the Form 1116 AMT might be causing the problem. We haven't had to pay AMT since I retired. Several years ago our return was flagged by the IRS and they asked for a Form 6251 to be submitted. Since I didn't owe AMT, nothing further happened. But ever since then, I have always checked the box to submit the 6251 even though not required to avoid IRS questions.
This year's return has been repeatedly rejected. The only thing I did this time was to uncheck the box to submit the 6251, which also deleted the 1116 AMT form, and it was accepted. I'll have to see if the IRS later requests the 6251.
