I understand what the program dose now. 

Transmitting first 5 characters or whatever is in the input screen is fine, however, the program actually makes an effort to convert the input "UNIT 26" to "UN 26" on paper / PDF version on CA return, but drops the "6" at the end, only transmits "UNIT2" or "UN2" to CA FTB is very misleading.

A diagnostic warning that only first 5 characters of the unit number in the input screen are being transmitted to CA FTB or part of the input is cut off will be helpful.
