Thanks for following up and your offer to help troubleshoot this issue. Meantime I was able to solve the issue myself ,though I think it's worth an update to your Maryland software. To solve the problem I started from scratch and watched my Maryland return carefully as I input data into my Federal return. What happened was as soon as deductions dropped my MD gross taxable income below the minimum level required for filing a MD return ($12,200 for single filers), Turbo tax deleted all subsequent entires on the MD form, ie, deduction method, standard deduction amount, MD state tax due, local tax rate, local due, and so on. In a more perfect world, Turbotax would've highlighted the fact I'm not required to file a MD tax return (for the given reason) rather than simply congratulating me for not owing any tax after it completed the state review with half the return blank.
