I filed with turbo tax last year but I believe I may have mistakenly filed the same 2017 w2s both last year and this year

If you filed a 2017 W-2 in your 2018 return, you will have to now wait until your return is accepted or rejected by the IRS.  If rejected you can delete the 2017 W-2, add anew one,  and refile.  If accepted, you should wait until you receive your refund for the filed return and then file an amended return to make your changes.  Amended returns are processed separately, they do not catch up to and correct your original return. Amended returns can only be filled on paper through the mail.  It takes the IRS up to 16 weeks to process them.  You can't file an amendment until the 2918 1040X is available.  Amend instructions after 2018 form is available:
