No payroll in 2020. S Corp started mid last year and planning on filing late S-Corp relief. You can file 2553 with the tax return and request late relief election. I believe he started the business before creating an LLC therefore a 1099 was issued under his name and SSN for the portion of payments, he most likely did not fill out the W9 for the business as an S-Corp and received another 1099 for the business using the EIN. I wonder if the company that issued the 1099 would be willing to correct it? In that case he didn't need to receive a 1099 at all. 

thanks! I have read the Kansas website and I am almost confident on how it's supposed to look. I can't figure out how to input in Proconnect. I will try support for that. The only doubt I still have is that the Kansas Sch S only asks for total income and Kansas sourced income. Technically, no income is sourced in Kansas.

Do you mind me asking why you ended up working with a representative at the data loss unit? It is the first time I experience this and what I have done so far is mail the return with a 10439 and an 8948. Should I be doing something else? 

As the deadline approaches I have had 2 customers with this. I had never had this happened before. I am also a bit concerned and wanted to let you know, you are not the only one. But I do wonder if it's happening more this year in general?
