"In TT Business, where can I find NOL calculation, NOL carryforward ?"
You can start by clicking the Federal Taxes tab, then click Deductions, and then the Start button to the right of Net operating loss carryover.
The foregoing procedure will bring you to the next page for your review (see screenshot).
Unless this is the trust's final year, that loss (or any portion thereof) will not carry through to the beneficiary(ies).
If this is the trust's final year, then the K-1(s) will show the NOL on Line 11 with a D code; the beneficiary(ies) will enter that information into their personal income tax returns.
