Cash in lieu of fractional shares after a reverse stock split

I received a $11.30 check after my stock (a mortgage REIT) did a 1-for-4 reverse stock split (as I understand it). The REIT’s trust company mailed me a paper Transaction Advice “as a result of the automatic corporate action processing of 3,[removed] shares of COMMON STOCK..” (I tore off my check from the bottom.) Where & how do I enter this in TurboTax? And do I have to enter a “basis? The paper Transaction Advice doesn’t show any.
