I'd ask for the SS card just to be sure.  Do all of the information returns have redacted SSNs?  I liked it better when we could use them as an extra verification.  I had one where the middle digits of the SSN were reversed on the 1099 (fortunately we had it right, the payer had it wrong).

Beyond that, what everybody else said.  Get an IP PIN (often easier said than done) or extend until you can.  Paper filing might be in your future (IMO that's not solving the problem, just kicking the can down the road but sometimes that's the best you can do).
