Screen 6 - Estimated Tax Payments.  Up at the top, third line down  - enter the amount applied from the prior year.

Screen 24(?)  14.2  -  That's where the 'refund' (and it is a refund, even if applied to the following year) is listed IF it's taxable.  I like to list the refund anyway with the detail of why it's not taxable for documentation.  Lacerte creates a worksheet on this that carries all the info from the prior year.
