Please check to see if your return was
rejected. One of the tests that the IRS applies on e-filing is to compare the name and Social Security number of each person on the return, and names changed because of marriage is a
common cause of rejection.
If your return was rejected for that reason, just go back into the return and change your name to your married name (the one that the Social Security Administration knows about). It won't matter if it's different from your W-2 so long as your Social Security number on the W-2 is correct.
If your return wasn't rejected, then don't worry about it this year, unless you get a Taxpayer Identity Verification letter, through which the IRS will ask you to verify who you are. Please respond quickly to that letter, because it holds up your refund.
Make sense?
