I had same problem with filing being rejected but when I changed the pay date from various to 12/31/2020 the filing was accepted so thanks to whoever figured out the workaround. Interestingly, I had a conversation with a neighbor who does taxes for others using another software product and he had the same problem that was also fixed by plugging in a date. So, it would appear that the problem is with the IRS software. Still doesn't excuse TT for not being more proactive in getting the IRS to fix their bug or at least letting its customers know about the problem and how to get around it.
