In error I did not mark that both my husband and myself were on a high deductable medical plan last year

[Exhausted2016]

Is it worth amending my return today to correct the fact that I failed to report to TurboTax that both my husband and myself were on a high deductable medical plans so TurboTax reported that I overfunded my HSA by $620 and I was charged a tax penalty?

I would say that amending your return to remove the penalty would be worth it, because if you were charged a penalty, you also carried over the excess to 2017, which will reduce your contribution limit next year.

As for "amend my return today", it doesn't matter when you amend a return, so long as you do it within 3 years. Today is not the deadline for amended returns.
