I filed my 2019 return and had an overpayment of $5,000 which I applied to 2020 estimated taxes, rather than getting a refund. Later I discovered a $2,000 error (overstated deduction) which will reduce my refund to $3000. I don't owe anything -- it just reduces my payment for 2020. But TurboTax e-file keeps telling me I need to write a check for $2000. How do I avoid that?
