Is there a way for me to file my federal and state tax returns separately, since I already filed my federal ones through the IRS site?

After filing my federal tax returns, after struggling to figure out the state ones, I decided to use TurboTax to finish it up. However, because I already filed my federal taxes, the state taxes got rejected with the federal ones. If I can’t file them separately, is there anything I can do to not have them be rejected?
