This is no designated place, in TurboTax (TT), to enter a 1099-S. Where it goes, depends on what was sold. Entering it in the "1099-B section" (Investment Income / Stocks, mutual funds, Bonds, Other) of TT is the correct way, in your case. Real estate is "other". Answer no when asked if you got a 1099-B.
When asked when you acquired this property, type the word, INHERITED. That will make the capital gain/loss long term.
The cost basis for inherited property is the fair market value (FMV) on the date of death. If the property was not used for personal use, by you (not the decedent), it can be treated as investment property and any capital loss is deductible. If you did use it for personal use, after acquiring it, check the box "any loss from this sale is not deductible" on the screen "Select any less common adjustments that apply"
