How can I find my 2018 state taxes from turbo tax to make sure they were filed?

State or federal?  IRS is federal.  And they didn't get your return or a tax due payment?

How to Access prior year online returns

If you can't get the side menus to open up to access the prior year..... You need to start entering some basic Personal Info in 2022 for the side menu to open up. Just continue a little ways into 2022. I had to go though about 12 screens.

If you used the Desktop CD/Download program then the only copy is on your computer and not saved or stored online. So you need to make and keep your own backups.

In the PDF of your TurboTax return, the last page of the federal return should be an "electronic postmark" that shows your name, Social Security number, the date and time that you e-filed the return, and the date that the IRS accepted it.

Did you efile?  Was it Accepted?  Maybe you didn't finish filing it or it Rejected.  When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc.  what does it say?

Then when you efile you get back 2 emails.  The first email only confirms the transmission.  The second email says if the IRS (or state) Accepte.d or Rejected your efile.  Check back though your emails if you have them.

Does the state say you did not file the return or that you did not PAY your tax due for 2018?   Your only proof that you paid tax due would be your own bank or credit card record.  TurboTax will not know if you paid; TurboTax will only be able to show if your e-file was accepted or rejected.  What does it say in your account?  Does it show that the state return was accepted or rejected?  Or--if it says "Printed" or "ready to mail" that means you did not e-file it and unless you mailed it yourself in an envelope it was not ever filed at all.  TurboTax does not mail it for you.   If it turns out that it was not ever filed, you can print it, sign and date it and mail it in with your payment for the tax owed.   It is too late to receive a refund for a 2018 tax return.

  You have to access your own account and/or  print it for yourself using exactly the same account and user ID that you used when you prepared the return.

Start a 2022 return online and enter some personal information  so that the menu on the left opens up and lets you access your past year returns.

Many people have multiple TT accounts and forget how to access them.  Log out of the account you are in now.

Or did you use the desktop version of TurboTax?  If so, the files are on your own hard drive or any backup device you used like a flash drive.
