You can look at the 1040.  It tells you how much is applied to the next year and how much will be refunded (lines 35 and 36).

Read the standard client letter and it will tell you which estimates have been scheduled for auto withdrawal.

If you EFiled the return after 9/15, the only ES payment that can be scheduled is the 4th one, all the other dates are too late, but I think those show up as red on the screen and wont let you schedule them.
