I received $670 less than my federal return said I would receive, and I never received a letter explaining why I got less
In another comment, you said your refund amount was supposed to be $1910. Look at your return and see if $1910 is the figure shown on your Federal Form 1040, Line 21a. Don't go by any total refund amount that TurboTax may have given you which might include a state refund, if applicable. If you're getting a state refund, it comes separately.
If it was the IRS that reduced your refund, then the IRS has been performing little correspondence the last few weeks. And their live assistance call centers are closed. When they reopen at some point, you'll be able to phone them for information.
Is there any message at the IRS "Where's My Refund" tool, that might provide a clue?
