In your open return, under Income & Expenses, click "Review" next to "Self-employment income and expenses", then "Review" on the "Your 2018 self-employed work summary" screen then click "Edit" next to "General info". Under Payments and identification, click "Edit" under Employer ID Number (EIN) , then select "No, I don't." on the next screen and Continue. (see sample screenshots below)
