I'm wrapping up my Missouri taxes and have an issue. I have a modest over payment of taxes to the state of $627 which I can validate and shows on line 49 of my MO-1040. I've also checked the box to apply ALL of my overpayment to 2026 taxes on MO-1040ES Wks, Part II, Line 2b. However, on MO-1040ES Wks, there's a number I can't understand and it is impacting my overpayment balance. In MO-1040ES Wks, Part 1, line 1e, regarding 2026 Estimated Tax options, there's an amount showing as "Equal to 100% of overpayment (no vouchers)" of $241, not the $627 from my return. Further, on MO-1040ES, Part II, lines 1 and 1f, both include the $241 amount, not the actual overpayment of $627. It then transfers this $241 to MO-1040, Line 50, showing that's the amount of my overpayment to apply to 2026 taxes. Lastly, the balance at the bottom of the schedule MO-1040, Line 53 is showing $0. The math for that line is Line 49 (showing $627) less Line 50 (showing $241) less Line 51 (showing $0) less line 52 (showing $0), which should leave a balance due of $386 - but it shows zero?? It is mathematically incorrect??? Also, if I click on the $241 amount in MO-1040ES Wks, Part II, Line 1 regarding the amount of overpayment available, to Go To Supporting Form, it takes me correctly to MO-1040, Line 49 but that balance is $627, not $241. This seems like an error in the software or either I'm doing something that is causing this error. Any ideas?
