How do I reduce this year's net capital gains using a capital loss carried forward from a previous year, in TurboTax Business Incorporated (2018)?
I am using TurboTax Business Incorporated (2018). The corporation has net capital losses carried forward from previous years (already entered on Schedule 4, line 200). How do I reduce this year's net capital gains using this capital loss carried forward? It seems like line 225 on schedule 4 is the right place, but that field seems to want to be calculated (or filled in from somewhere else) by TurboTax; I can't find where line 225 gets filled in from.
