Estimated Tax Penalty - appears incorrect + Where did my overpayment go

2 issues: 2023 Form 1040 Line 38: Line 34 shows over payment of $542, Line 36 amount of refund to apply to 2024  is $38 (which is what I thought my over payment/refund was at that part of the TTax input), and Line 38 shows an estimated tax penalty of $504.

(1) Where did my $542 overpayment go?

(2) Why is TTax showing showing an estimated tax penalty on line 38 (coincidentally the amount of line 34 minus line 36).

 

Do I need to start a completely new Fed return to clear this up?

 

Thank you.
