My client is a sales rep and has been receiving a Form-1099 from his employer for the past ten years.  This year his employer stopped reporting his earnings under his social security number (mid year) and insisted that my client secure an EIN (which he did) and the employer reported the remaining earnings during 2019 under the new EIN.  Bottom line: my client has two Forms 1099 from his employer. One reporting income under his social security number and the other under the newly EIN.  Do I input both 1099's received (from the same payor) as self-employment income to existing Sch. C ?  Not sure how to handle this and have seen numerous examples of Payors insisting on this change due to new restrictions on "who can receive a Form 1099-Misc. for self-employment income". HELP!
