You would only need to print and mail the forms if you were instructed to do so before filing. Otherwise you're good to go.
How long does the return typically take, if I am receiving it through check by mail?
You should double check your efile status here <a rel="nofollow" target="_blank" href="https://turbotax.intuit.com/tax-tools/efile-status-lookup/">https://turbotax.intuit.com/tax-tools/efile-status-lookup/</a>
Or does you Account say Ready to Mail ?
Sorry but Ready to Mail means you have to actually print out your tax return and mail it to the IRS yourself. So it has not been filed yet. You can try to switch to efile https://ttlc.intuit.com/replies/3985787
