First, did you efile? If so, and if you used Online TurboTax, log in to your account and confirm at the Tax Home that your efiled return was accepted.
If you filed by printing out and mailing the return, it's too soon to be using the IRS WMR tool. Even in the best of times a mailed paper return takes at least 4 weeks to show up in that tool, and with the Coronavirus there is a longer delay, as the IRS is not currently processing paper returns.
When using the IRS "Where's My Refund" tool, be sure you enter the correct SSN and filing status.

Use only the Federal refund amount. Do not use any combined "total refund" figure that TurboTax might have given you 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.
You can also try phoning the IRS refund hotline. I've seen it work for some users before when the WMR tool didn't.
