No one here can access your file, you need to contact customer support.
If you have received no state or federal refunds, it sounds like you probably never filed, or your return was rejected and you never fixed it and re-sent it. You get rejection notifications by email but sometimes they get caught in a spam filter, or you might have mis-typed your email address when setting up your return. If your federal return was rejected for a technical reason and never fixed, then your state tax return was never transmitted to the state.
You can also request transcripts from the IRS to see if they have a return on file for you. https://www.irs.gov/Individuals/Get-Transcript
It's also possible that your refunds were paid but offset for other debts, but in that case you should have gotten a letter from the IRS or the state. Or, if your refund was held for verification, it would not be paid and they would send a letter. Have you been using your correct mailing address on your tax return—where you want to get mail, not necessarily where you lived during the year.
If you received a state refund but no federal refund, this would also sound like an offset or verification issue and you should have gotten a letter.
If you can confirm that you never filed, you can print, sign and mail your returns now. Use separate envelopes for each return, don't forget to mail your state returns as well, and maybe use a mail service with tracking.
