My daughter is in college and filed her own tax return. It seemd like I could file her as a non dependent to receive EIC?

Did she file and say no one can claim her as a dependent?   Is she is full-time student under the age of 24?  If so, she made a mistake that is going to block you from e-filing and claiming her as a dependent.  But you can claim her and file your return by mail.  She will end up having to amend her own return after it has been fully processed.  Kids do this to parents all the time, sadly, because they do not know what a mess they are creating.

MY DEPENDENT SAID HE COULD NOT BE CLAIMED

Your dependent filed a return without saying he could be claimed on your return and your return was rejected?  AFTER his return has been fully processed and he has received his refund, he has to file an amended return that says he can be claimed as a dependent on someone else’s return.  Amended returns must be prepared on a Form 1040X.  It takes the IRS at least four  to six months to process an amended return.

 Meanwhile, since your e-filed return has been rejected, you now have to print and mail it in to the IRS.  You will not be able to e-file. You do not have to wait for your dependent’s amended return to be processed.  Remember that when you mail a return, you need to include copies of your W-2, etc. with your return.  Use a mailing service like certified mail that will track it so you will know that the IRS received it.
