First time canning my ball wide mouth jar may have gone into the water bath with the lid depressed. Must it go in with the lid in a popped up position? Now cooled, it makes a thud sound when tapped with the side of a spoon, but the lid is stuck to the jar. Any opinions on if this is properly sealed?

It should come out of the bath with the button up and as it cools, the button will pull in with a satisfying pop.

If that doesn't happen the jar might be sealed, but there just isn't a good way to know short of forcing the lid.

If the lid is stuck firmly, without jam having leaked out onto the seal, I would be confident in the seal.

If you really want peace of mind, you can clean the rim, replace the lid with a new one, and process the jar again.
