How to enter accrued interest on HH bonds on Maryland state form to stop it from being counted as income?

This did not answer question. 1099-INT only shows accrued interest paid, accrued interest reported and Federal tax withheld.  There are no boxes for the state.

You have not answered the question!!!!!!!!!!

You don't have to enter HH bond interest into your Maryland return. If you entered it properly as HH bond interest accrued in your federal return, then it won't show up in the state return as it is not taxable by Maryland.
