Can't change a business deduction.

What type of return are you doing, business (e.g., 1065, 1120-S) or personal (e.g., 1040, Schedule C)?

What is the deduction and did you already file and are now amending?

Which deduction?  Are you filling out schedule C?  If you are trying to correct an Expense, you can probably get to it here…..

Insurance Expense on Schedule C 1040.  2025, not yet filed.  Only option I have found is ‘update’, which does not allow me to change amount

Download 

specifically, is the insurance for medical insurance on you, your spouse, dependents or employees? That is handled differently.  what kind of insurance? 

Medical   I need to change the amount on that line

Thanks everyone.  Going to Forms and right clicking on the amount gave me a over ride option.  Was able to change it.  Thanks again  

I tried everything to change this amount.  The override is the only thing that worked.  Thanks

FYI -   Self Employed Health Ins will not show up on Schedule C and not reduce any SE Tax on a net profit.  It does reduce your 1040 total income for the regular income tax.  

Self-employed health insurance deduction goes on Schedule 1 line 17 (which goes to 1040 line 10), as long as the expense is not greater than your net self-employment income. If it does exceed your net self-employment income it gets split automatically. An amount equal to your net self-employment income goes on Schedule 1 and the remainder gets added in to medical expenses on Schedule A.  Medicare plan B payments are qualified as Self-employed medical insurance premiums and should be entered under Business instead of in the SSA-1099 Social Security Benefits section.

It will not show up on Schedule C and not reduce any SE Tax on a net profit.  It does reduce your 1040 total income for the regular income tax.

What kind of insurance do you have?  If you have a marketplace plan…..You only enter it from the 1095-A.  When you enter the 1095A there should be a box to check for self employment.  If you enter the 1095-A and select the "Self-employed and bought a Marketplace plan" box, it will automatically include those premiums in the SE Health Insurance section. So you shouldn't enter it again on schedule C.

I have the Home & Business Desktop program.  6/6/26  I went though the steps.  It is in the same as before.
