Paper filing, Ohio return says attach any 1099(s) and copy of all supporting documents?

I asked the Live expert during filing, will I need to attach any extra forms to my Federal or my  (OHIO) state return, she said only your W2 and Schedule C.  But then......

Then on my printed return of my paper filing it says please also attach any 1009(s) AND a copy of all other supporting documentation (Including worksheets, if applicable) used in the preparation of the Ohio IT 1040.

 

The 1099(s) I have are both 1099-S from sales of real estate. to be clear.

Do I attach these 1099-S, and what about documentation and the worksheets used in preparation of the Ohio IT.

I have no idea what they are saying, where to find the documentation if so, so please be specific on what I need to do . Thank you
