After you file

You filed by mail?

TurboTax will not know anything about your mailed return, and will continue to show “Ready to Mail” on your account.  TurboTax will not know that you put your tax return in an envelope and took it to a mailbox.  TurboTax does not get updates on mailed  (or emailed) returns.

Wait about 4 weeks from when you mail a return and then you can check the status on the IRS site. https://www.irs.gov/refunds

State returns have to be mailed to the state.

As for only filing with part of your income:

ALL of your W-2’s and/or 1099’s were supposed to be on the same tax return.  Remember that next year and do not e-file until you have everything.  Now you have to prepare an amended return to add that W-2—and the process will take months.
