How do I correct the TurboTax form which is not calculating my total tax payments on the NY State return (line 76). Pmts are there on lines 63-75, but no total. Help?

I'm owed several hundred dollars.  TurboTax also leaves all the lines for payments due/owed after line 76 at $0.  So I'm getting no refund but it also doesn't say I owe.  Looks like their calculator broke!  Oh, and the return was "checked" and considered complete.
