Please explain carryover of unallowed expenses on form 8829

Again, because my business lost money in 2024, the amount allowed for business use of the home (form 8829) is less than what was spent. This high spending was mostly due to an excessive home insurance premium (rates in FL have gone nuts). Line 43 refers to a carryover to 2025 of unallowed expenses. How does this work? Will this show up automatically when I transfer my data to next year's return using Turbotax? What if my business shows a loss again next year (I hope not)? Thanks.
