2 properties went into 1031 exchange, basis for leftover fund

[Jennie Chen]

I sold 2 properties going into a 1031 exchange. it looks like i might have some leftover funds that will be unused and taxed on capital gain. my questions are:

1) do i have a choice which property's proceed that excess belongs to, in order to have the minimum capital gain/depreciation recapture? 

2) want to confirm that my operating losses from other properties (passive losses up to 25K, given my gross is low) this year can be used to offset the capital gain (but not depreciation recapture). is this understanding correct? 

thank you very much.
