As
@RuntheMouse stated it is the Interest Saving Payment.
As long as you pay that there will be no interest until it tells you the interest period is up somewhere on your statement.
Unlike some credit cards that offers 0% interest, Chase does not divide your purchase by six to add to that payment amount. Basically the amount of the interest savings payment is the amount of all your purchases that don’t qualify for 0% interest plus one or two dollars.
If you’re trying to do a budget, take the number in the interest balance and divide by five and pay that amount in addition to the interest savings payment for no surprises otherwise you can just keep that money in a HYSA and pay the whole thing when due.
