in desktop I was able to skip entering the FEIN
however, if Turbotax demands an FEIN try entering a dummy # like 36-1234567
I don't know why TT wants an FEIN when it's, as far as I know, not transmitted on an e-file and does appear on schedule B whether e-filing or filing by mail
you also have the option of contacting TT and complaining and asking them what to do. however if you are using the free version there is no support
5am-5pm Pacific Time (8-8 Eastern) Monday - Friday
