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!!

Here it is, 2021, and the problem still exists, exactly like you stated in 2020. Come on TT, "get with the program"
