I never received my federal refund for the 2019 tax year and never got a letter or anything explaining why. When i try to track it it says there is no infomration

 

After you file

Was your 2019 tax return Accepted?  You have to call the IRS, since TT receives no further information after a return is filed and accepted. 

After you file

 Did you efile or mail your return? When? They didn't start opening the mail until June that was stacking up. Back in March the IRS closed their processing centers and stopped processing mailed tax returns.
See this IRS page for the latest information

If you efiled....Was your return Accepted?When you efile you get back 2 emails. The first email only confirms the transmission. The second email says if the IRS (or state) Accepted or Rejected your efile.

Then only the IRS can tell you. IRS Where's my refund https://www.irs.gov/refunds/
Make sure you are using the refund amount from your actual federal tax return and not the combined amount Turbo Tax showed you at the end. That was for federal and state combined.

When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc.  what does it say?
