I am seeing a number of posts like this.
1) The IRS must stop sending payments on Jan 15
2) the IRS won't begin accepting returns until Jan 27
3) if the payment doesn't arrive, it will be reconciled on your 2020 tax return.. Just fill in the requested amounts in the Federal Review Section and then look on Line 30 of Form 1040 where the credit will appear. It has the affect of increasing your refund (or reducing what you owe)
Suggest waiting until Jan 27, at the earliest, to file to give the mail time to clear. That will minimize your headache if you file prior to the 27th and the check arrives a day later, which we all know is Murphy's Law and likely to occur!
