S-Corp - K-1- box 17, "AC" says see stmt. Statement lists "adjustable tax income...$XX". Is this the number I enter in box 17 next to "AC"?

Yes, you enter the amount on the statement in box 17 with code AC.

there is no number on the k-1 box 17 next to AC.  On the statement it says "adjustable taxable income" with a number.
