MD tax law requires line 48 on Form 502 be checked when tax due is more than $500.00. This fills in Form 502 UP, ESTIMATED TAX AND ENTERS
MD tax law requires the box on line 48, Form 502 to be checked when the tax owed is more than $500. I owed more than that in 2023 but TurboTax did not check that box. Doing so brings up Form 502UP, estmated tax and enters a tax back on line 48. As a result of this error, I now owe over $200 for underpayment of estimated tax.
