I was unable to recover the 2FA on Android just as Text posted. The error I got was different but it was an error. I tried it the first and second time with the same error. Test is using a mobile phone for it.
I also tried to import a 2FA seed phrase into the android version of electrum to see how it works and got the following error. 
I cleated electrum's cache to see if it solves the problem. It didn't and I got the same error again.
After that, I cleared all electrum's data from my device and then imported a 2FA wallet. It worked.
It seems that once you create your first wallet in electrum, it no longer allows you to import a 2FA wallet.

I tried what hosseinimr93 posted and it worked. If you do not have any other wallet on the wallet app, you can just reinstall the wallet or delete the wallet storage data, that will make your wallet new as if you have just downloaded it. To do that, long press on the wallet app and select app info which is represented with i within a circle on Android 14. Or just go to phone settings, select and click on app management to look for Electrum app and go to its wallet information. I tried it and it worked.

Thank you very much for the help, I appreciate it.
I have already disabled the 2FA, but when I checked the wallet details, this is what appeared on the screen:
When I click "show report contents," this appears:
I confirm that there's no longer any extra free when I send.
