3 month bill to 10-year yields
The Fed itself has highlighted its preferred measure of yield curve inversion as 3-month bills to 10-year notes.
The April 20 bill yield fell below the 10-year note yield for a minute or two at 1600 GMT (noon ET). There is talk that this was inverted all day but it only happened for a brief period. It still happened but only very briefly and narrowly.
That said, the curve is inverted deeply out to 7 years so we might be splitting hairs.
