CME busy

Please help!! At the end of last year I used my remaining CME allowance and bought a CME4life course that came with a $1000 Amazon gift card. I just received an audit from my company that wants to know “whether a gift card was included and if it was used for learning materials”. Additional documentation is needed.

Do I just buy a bunch of $hit on Amazon now pertaining to my job to cover my butt? Or just plead ignorance? I’m kind of spiraling!!
