CP11 tax calculations

[pakos]

I received a CP11

It says my tax calculations are correct - but says my payments and credits (line 25d and lines 27, 30, SCH3, 8, 10, 11, 12f) add up to a total less than (878$) than the total tax from line 24.

I talked with a turbo tax help person and can not find anything wrong.

It says to call to dispute but of course no one is answering the phone.

Can anyone help on what I should do????

Thanks
