So did you print, sign, date, and physically mail the return yourself to the IRS? TurboTax does not mail it for you.
And if you also had a state return, hopefully you mailed the two returns separately--the Federal return to the IRS and the state return to the state tax agency. We have seen some filers mail both to the state by mistake and nothing to the IRS (or vice versa).
Normally it's best when mailing things to a tax agency to use a method that has tracking such as certified mail, priority mail, etc.
So if you DID physically mail the return correctly to the IRS, you can use the IRS "Where's My Refund" tool. Is it saying it can't find your information?

First be sure you are using the tool correctly; i.e., correct SSN and filing status.
For the Federal refund amount, use only the Federal refund amount. Do not use any combined total refund figure that includes the state refund.
Look at your actual 2019 return to get the Federal refund amount. Be sure you are using what is displayed on your Federal Form 1040, Line 21a for the Federal refund amount.
If it still doesn't find your information, you are going to be in limbo, since you won't know if it's been received (if you didn't use tracking), whether it's hung up in processing due to Coronavirus, or what. And the IRS call centers are closed for the time being.
In the best of circumstances, it normally takes 4 weeks for a mailed return to show up in the IRS WMR tool. It "normally" takes at least 6 weeks to get a refund after a mailed paper return. With the Coronavirus situation, however, all bets are off, with the IRS severely limited. In fact, with so many personnel on leave I don't believe they are processing any paper returns right now.
