I am 100 service connected disable veteran and want to include the retirement pay income tax deduction per state of Maryland. Need help to include this exempt deduction.

According to https://veterans.maryland.gov/maryland-tax-benefits/

Military service connected disabled veteran allow to subtract up to $5000 from their retirement income for State tax filing. I met this criteria but could not find anywhere on Turbo Tax to include this exemption. Please advise!
