I cannot tell you what to do. I can only tell you what I've done. "Small Business Consultant" is my job title. I NEVER take 1099's. If they ask for them, I just say, oh, I got so many, I didn't know you needed them all. I made a list, here's the total on each 1099.
They have always prepared from my list.
My list DOES include the provider's Federal ID number (found on the 1099).
You are required to attach w-2s to the return; you are NOT required to attach 1099s.
Same thing with expenses. I give them the list, they go by that.
