If you are currently in the Deluxe edition, to enter business related expenses, you will need to upgrade to the Self-employed version.  Without any related expenses, you can stay in Deluxe and complete your filing. Continue follow prompts in Deluxe, it will take up to the upgrade. 

Your self employed net profit will show on line 3 of Schedule 1 and line 8 of your Form 1040.
