What is reject code f8960

My federal return keeps getting rejected and I don't understand why am I getting this reject code. Form 8960 has to do with Rental income loss or gain and I've never had rental income. Like ever. Turbotax's suggestion is to 'wait a few weeks and try again' or print the returns and mail them. So let me get this straight... TT has been paid to file taxes, although they can't. Their solution is to do it myself. How about a refund then??
