I do not know if this will work, but I too was having a problem last year with not being able to populate the federal stimulus fields in turbo tax. If you are like me and others, we don't like entering our SS# in the field into Turbo Tax. This was what was causing the stimulus field to not populate for me, not having a SS# where Turbo Tax requires there to be one entered.
I suggest entering you SS# and see if that works. You can always change the last 4 digits to a dummy number when saving the file, which I always do using an external hard drive or thumb drive.
Good Luck
