Can't unmark estimated AGI (Line 5, Col 1) after correction on my Carryover Worksheet

Turbotax 2024 desktop version. Carryover worksheet, line 5 column 1. It keeps telling me that this field is marked as estimated, but there is no field or check box to unmark it. It won't let me file my federal return until I fix this. Is this a software bug? Can anyone help? Don't know what to do. Thanks.
