I am unable to efile because it wants a zip code for an employer. We did not file a W2. How can I override this ?

THIS GUIDANCE WAS PROVIDED TO ME BY TURBOTAX.  IT WORKED FOR ME.

I HAVE TT HOME & BUSINESS LOADED ON MY MAC FROM A TT CD. 

IF YOU HAVE A NON-APPLE COMPUTER AND/OR DOWNLOADED TT FROM THE WEB RATHER THAN FROM A CD, THERE MAY BE EQUIVALENT STEPS.

   "If its truly an erroneous W2 and not something you need, then you can delete it from the Forms. 

• Load up your tax return on your computer
• Switch to "Forms" mode - the icon in top left corner of your program
• You should now see a list of the forms in your return on the left-hand side of the program
• Find the Form W2 you wish to delete and click on it
• This should bring up the W2 form in your active window
• Click on the Forms option on your menu (top of your screen you should see your Apple icon, then TurboTax, then File, Edit, View, Forms, Easystep, Flags, Window, and Help - click Forms)
• There should be an option to remove the W2 form from the dropdown menu under Forms

I had the exact same problem on my 2019 tax submission when I went to file.  It was very frustrating as, like you, I have been retired for years and don't get W2 forms, only 1099-R forms.  I couldn't get out of this loop which kept me from filing.  Out of frustration, when it asked for my employer state, I just put in the state I was in, and for a zip code, I just put in my home zip.  It then allowed me to finish filing.  This is a bug in the system and it needs to be corrected by  Turbo Tax.  To me it is a "no brainer" if one files the taxes using 1099-R forms and social security forms -- that they are retired.  Anyway, I used your advise after the fact and went into Forms, and manually deleted the W2 form.  

Come on Turbo Tax, lets get this "bug" fixed!!
