I already filed my taxes, but I just received my college taxes in the mail. Is it to late to file these taxes?

You would have to file an amended return

Yes, you can't make any changed if you already filed your return. 

If your return is pending, you can't make any changes until it's been accepted or rejected by the IRS. If the IRS rejects the return, you can add your 1098-T and resubmit the return. 

If the return has been accepted, wait until your return has been fully processes and you received your refund ( if you are expecting a refund ), then amend your return. 

Follow the steps to amend your return:

1. Sign in to you account.
2. Scroll down to Your tax return & documents , select 2019 and then Amend (change) return. 
3. Select Amend using TurboTax Online.
4. follow the instructions, your refund or tax due will change to 0. This is normal on amended returns.
