I have tried both 2022 and 2023 dates but the 2021 electronic filing keeps getting rejected. And I removed the check at Enable Conversion Error Checking. Intuit claimed they were going to have this fixed in 3 weeks. Well time is almost up--2023 electronic filing began on 1/23/23. 

Three weeks is a long time for practitioners to give excuses to our clients. Clients never really believe that there are software issues. They just want us to waive our magic tax wands and complete their taxes.
