Are you expecting a check for your refund or does Turbo Tax say Ready to Mail for your return?
Printed or Ready to Mail means you have to actually print out your tax return and mail it to the IRS or state yourself. So it has not been filed yet. And it will always say Ready to Mail. Turbo Tax doesn’t know if or when you mailed it and the IRS doesn’t update Turbo Tax when they get your mailed return. You can try to switch to efile.
