I don’t know what you mean by making changes to federal section. The amendment starts everything back at zero refund. You add the business expenses under “business income and expenses “section. It’s only adding to the state refund but federal refund is still zero. Only when you add charitable contributions does the refund add to both the federal and state refund amount. Is there a maximum limit on business expenses you can enter as it pertains to federal refund whereas charitable contributions is more personal and thus no limit?
