I submitted my w-2’s to turbo tax before i was able to add my tuition statements to the schools i attended. what can i do?

If your parents are claiming you as a dependent, they may have to put the 1098-T Tuition form on their tax return.

See Can I claim college or education expenses if my parents paid for them?

Otherwise: 

If you e-filed your income tax return(s) and:

• They were accepted, you won't be able to edit your information You'll need to amend. 
• If your return gets rejected, you'll be able to edit. See How do I fix a rejected return?

Note: the 2019 amendment form 1040-X hasn't been released by the IRS so you won't be able to amend your tax return until then. See When will my forms be ready?

Once the forms are ready, see How to amend (change or correct) a return you already filed
