1099-R box 7 code not listed in drop-down menu... now what?

The drop down list for box 7 doesn't look like this?  What code do you have?  Do you have 2 codes listed?  There are 2 boxes for box 7 if you have 2 letters or numbers listed.  

What is the code that is not listed?

Re: 1099-R box 7 code is a Y which is not listed in drop-down menu.

Now I I cannot finish my tax!

There is no code "Y" for box 7.    Are you sure that the code is not a "7" - the same as the box number and the Y is in the IRA/SEP/SIMPLE box next to box 7 to indicate Yes it is an IRA?
