Deductions & credits

Yes, our 3 year old was in a daycare facility all of 2021 so my wife and I could work.  We're married, filing jointly.  I'm just concerned since when I put the total amount we paid into the dependent care portion, the refund amount went up significantly and I don't remember it going up like that last year.  So didn't know if something changed in claiming dependent care since it added so much onto our refund.  Am I correct that there was a change and that's why the refund amount went up so much?
