I mailed my federal return as printed from Turbo Tax and still have not received my refund. How much longer does it take to process my return?

The IRS was not processing paper tax return for several months due to the pandemic and limited. staffing.

They have only just started processing approximately 11 million paper tax returns as they were received.

We’re experiencing delays in processing paper tax returns due to limited staffing. If you already filed a paper return, we will process it in the order we received it.

Do not file a second tax return or contact the IRS about the status of your return.

Oh ... you have quite some time to wait this year ... the IRS is 3 months behind in processing mailed in returns due to the earlier covid shutdown.  Check the IRS site once a week until your return is in the system for a progress report ...   https://www.irs.gov/refunds
