I have filed returns before with1031 exchanges.  This is the first with Proseries.  Stuck on one entry on Form 8824.  Specifically, on the Summary Smart Worksheet, Item L, "Cash Received".  Is this

1.  The amount realized from the sale of the relinquised property?

or

2.  Cash received in addition to the FMV of the replacement property?  In this case, the taxpayer just received the replacement property with no debt assumed so the value on Item L would be $0.
