Questions about the calculator and tradeins

I have 2 questions specifically related to Hyundai. On the calculator where would you put the $500 downpayment match? Is it the same as the boostup match? Where do you put the uber $1000 rebate.

If I am trading in my old car(which was purchased), can I ask them for cash instead of putting it down on the lease(which I know is a big No No here)?

Carmax is offering 5000( after payoff) cash while dealer is offering 5800 but they are trying to roll it into the downpayment for the new lease.
