Section 179 Deduction Disallowed

I have 3 rental properties. One had a major renovation in 2021 and therefore showed a loss. The other two showed a small profit, however with the renovation the 3 rentals show an overall loss. My Section 179 for carpet ($2300), kitchen cabinets ($350) and water heater ($900) were disallowed for 2021. Each were entered separately. I know the disallowed can roll over to next year. However I am still trying to figure out why it was disallowed in the first place. I found this on another question: Your Section 179 deduction amount can't exceed your net business income for the year, but if it does, you can carry the excess over to a future tax year.

 

Does this mean because my 3 rentals shows an overall loss for the year (2021) is why the Section 179 is being disallowed for 2021?

 

Thanks in advance for the help.
