Filing a return for a decedent.   No refund so 1310 is not necessary. 

 Entered the DOD on proper input but I keep getting a diagnostic that the phone number on the 1310 input is incorrect.   There has been no input for 1310 as none is necessary.   I have tried inputting information on the 1310 to clear the error and nothing seems to work. 

I even reloaded the software and nothing!
