2. Click on Basic Information to expand that category then click Residency
3. Select Full-year resident
4. Click Maryland again
5. Click Miscellaneous Topics to expand the category and then click Military Information 
6. On the screen titled Maryland – Non-Maryland Military Income enter your tax exempt military income and click Continue
7. Select ONLY military income filing a joint resident return with a civilian spouse with any income and click Continue
8. Enter the amount in either Taxpayer’s nonresident military income or Spouse’s nonresident military income and click Continue

This will transfer the amount to Line 7 on Maryland Form 502.
