Solved
I have a federal tax due and chose to pay by credit card but there's no option as to the date I want the charge to take effect. When will my card be charged today (say, if I give authorization today) or on 4/16/18?
Not today, but before 4/16/2018. Generally, the credit card will show the funds removed within 24 hours or so from when your return is Accepted. If you still don't see the charge 7-10 days after your return has been accepted, call IRS e-file Payment Services at 1-888-353-4537 or contact your state tax agency, as appropriate.
