I filed my taxes online and I am at a screen that tells me my taxes are ready to mail I already printed them off and mailed them in what do I do next

Nothing. Wait for your refund.

The IRS Where's My Refund? lookup service provides a specific, personalized date for your tax refund.

Turbo Tax will always say Ready to Mail.  They don't know when or if you actually mailed it and the IRS doesn't tell or update Turbo Tax when they get your return.  

4 weeks after mailing you can start checking IRS Where's my refund

Did you get a tracking number from the post office?  And mail federal and state in separate envelopes to different places?
