The only thing I turned in when I stepped aside as an elder was my "Pay Attention" elders' book. No one asked for anything else.
Notes were placed inside the manila and kept in congregation files. But during a particularly long, drawn-out judicial committee, the Society had us answer lots of questions about it in writing. I used my computer to type it all up. The final version went in the manila, but the rough draft remained in my meeting bag for a long time.
By the time I came across it, I was no longer an elder--and for some reason just kept it with all of my Public Talk outlines.
