You can claim the Lifetime Learning Credit without a 1098-T, but not the American Opportunities Credit.
I'm not sure what you mean 'you mistakenly filed a 1098-T'.
This should not slow down your return, but you will want to correct it so you don't get an IRS notice once they are not able to match your numbers with the numbers reported to them by the school.
