I filed our return on the 9th of January. It's still pending right now. I'm wondering how long it will take to be approved

The IRS will not start accepting or rejecting any 2020 federal tax return until late January.

Once Accepted (meaning received) the tax return will be processed and then the tax refund Approved and Issued.  This procedure could take about 3 weeks after the return was accepted.  Unless the IRS finds some discrepancies in the filed tax return and then it can take much, much longer.

It will say Pending until the IRS either accepts or rejects your return which won't be until after they open on Jan 27, 2021 .  Be patient and watch your emails.

Even if Turbo Tax lets you submit your return they will just hold all the returns until the IRS opens filing on Jan 27, 2021 or later.  So there is no hurry.  And a lot of people who file early find out they have to amend later like when they get their actual W2 and 1099 forms.  Or they get more forms than they were expecting.
