What would be the net sales price for the sale of "unrealized refinancing fees points paid at closing" related to my rental property?

I closed an amortized asset in my rental property which were points I had paid at closing for the original mortgage. The remaining amount of this asset was transferred as a miscellaneous expense on schedule E, which I am declaring as as a lump sum for tax year 2021. When this transferred from my federal return to my PA state return, this "expense" is listed in the gain/loss section. It shows me the cost basis, which is the amount I am expensing when this asset was closed, but it is asking me to enter the "net sales price" for this capital expenditure. What do I enter for the net sales price?
