Maryland Military Retirement is now a $15,000.00 deduction versus $5,000.00. I cannot update form 502R because it still shows $5,000.00. How can I update to $15,000.00.

You must be at least 55 years of age by the last day of the tax year (2018) in order to qualify for the $15,000 subtraction from Maryland taxable income. Otherwise, you qualify for the $5,000 subtraction.

TurboTax will choose the correct amount based on your age.
