I used the IRS app to track my refund and have entered the same information for almoat 2 weeks and now I'm trying to do so and it says information does not match for aome reason. Why is that?

That IRS tool has been squirrelly a lot as a refund moves around in different stages of processing.  If it was finding your info previously, then you know you were entering the correct info at one time.

Use only the Federal refund amount.  Do not use any combined total refund figure 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.
