I filed federal by mail because my birthday was incorrect. The SSA corrected the problem, can I now e file for faster results

No, don't e-file after you have already mailed your tax return. It will either be immediately rejected or delay the processing of your refund. 

Attempting to e-file your return, after mailing them, may result in the IRS rejecting the e-filed return due to them thinking someone already filing using that name, social security number and birthdate.

Additionally, if there is a refund due, submitting two returns will slow down your receiving your refund because a person will need to investigate why two returns were received.
