Printed means the tax return has not been e-filed.

Verify the status of an e-filed tax return using this TurboTax website - https://turbotax.intuit.com/tax-tools/efile-status-lookup/

If the website indicates Rejected or No Record Found for the state return then it was not e-filed.  If you did not print and mail the state tax return then it has not been filed.
