The online link is your best option to track your refund. I have attached a link with more answers from the IRS as to why your refund may be taking longer to process.
There is a delay in processing the returns at the IRS due to Covid-19 and social distancing policies in effect.
Do you mean your Refund? Did you efile or mail your return? They just started processing mailed returns that have been stacking up. See this IRS page for the latest information

If you efiled....Was your return Accepted? First double check your efile status here

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?
When will you get your refund,
