I was operating as a sole-proprietor from Jan-Nov in 2019. In December 2019 I opened an LLC/S-corp and started doing business through my LLC/S-Corp. The problem is when the company I contract with sent me only one 1099 for 12 months' worth of income in my S-corp's name and EIN number.
How do I separate out the 11 months of income that wasn't S-corp income but instead sole-proprietor income?
