Retirement tax questions

Thank you. I followed your suggestions and discovered that the account holder did have a 1099R on line for that distribution- Now that brings me to another question- Neither of the 1099Rs has an amount for box 16 Maryland withholding. On the CSA-1099R with the yearly amount it does have Maryland state tax withheld, but does not have MD tax distribution. Do I leave it blank?Is MD distribution the same as MD witholding- there is no box 16.png
