you may be a victim of identity theft.  sorry, but you can no longer e-file. you must mail in your return and include form 14039.    

https://www.irs.gov/pub/irs-pdf/f14039.pdf

• If you checked Box 1 in Section B of Form 14039, are unable
to file your tax return electronically because the primary and/
or secondary SSN was misused, attach this Form 14039 to the
back of your paper tax return and submit to the IRS location
where you normally file your tax return.
