My wife has a percentage in Sub Chapter S Corp. The K-1 Form 1120-S contains AD code with no entry in Box 17. Turbo tax will not allow Code AD in Box 17

Turbo Tax will not allow me to enter a Code "AD" in Box 17 of form 1120-S.  My wife received a 1120-S form for her percentage in a Sub Chapter Corp.  The Code "AD" amounts are detailed on an attached statement received by her showing her percentage of Fed Tax withheld from two separate 1099-R's received by the Corp. She also received copies of the Corp.'s 1099-R's received by the Corp.  How do you enter this information in Turbo Tax.
