It is 1/27/2020, why does my return still say pending and I filed 1/8/2020? When will it start to process

The IRS will start processing returns sometime on Monday, January 27, except for a few test returns that they pulled early.     There's always a backlog when they first ramp up each year so you may not know anything for 24-48 hours or longer.   There's no way to know yet how smoothly that will go.   They pull returns from TurboTax in batches and in no particular order as far as I know.

You can keep monitoring the efile status at your Tax Home page.  You should also get an email when it's accepted or rejected.
