Will I be fined for filing my federal taxes twice?

I started filling my federal taxes with Turbo Tax but ran into some issue trying to file my state taxes. The only option I had left was to file by mail for my state taxes but I didn't want to, so I filed my federal taxes with a different company thinking that I'd be able to come back to Turbo Tax and only file my state taxes (the other company does not do multiple state filings). Well, I came back to Turbo Tax and tried to clear everything and start over so that I could only file the state taxes but I couldn't clear it because I've already registered my taxes. So, I gave in and tried to click the option of filing my state taxes by mail, but it wouldn't even allow me to do it for my second state because I've already selected to receive my refund through direct deposit.
