I was having the same issue when doing the E file on paying $25 for State return. Called the Helpline and told the possible
problem could be my billing zip code. After adding the additional 4 digit to the zip code, still rejected my credit card.
The agent then told me I might have problem with my credit
card, I tried another 2 cards and same problem.
Finally I used my wife’s credit card and went through.
You might want to use another family members’ credit card
to temporarily resolve the issue for the time being to get your
tax filing going. Certainly not get stuck in the middle of process, like the last step on E filing.
