I cannot figure out how it is doing the math on either my federal or state filing.   I entered my self-employment income in Wages & Income and did not include my Marketplace premiums as an expense there.  I put my prescription and doctor visit costs in Deductions & Credits.  I entered all of the data from my 1095-A in the section dedicated to health insurance from the Marketplace, and I answered in the affirmative that I am self-employed and bought a Marketplace plan.  In the Federal deductions and credits summary, the Medical Expenses line appears to show a sum of those health/dental claims and the premiums I paid for my Marketplace plan (1095-A column A minus column C).  But the amount that appears on that line is a few hundred dollars lower than it should be.   I went back and deleted the data from my 1095-A, leaving just my health/dental claims, and the amount on the Medical Expenses line is correct.  Then I deleted that and retyped the data from my 1095-A, and the amount that appeared was incorrect by a few hundred dollars again.  I tried deleting and re-entering my 1095-A amounts several times, to no avail.  I also tried to delete the 1095-A form and re-enter it, but that did not change the miscalculation.  I even cleared my entire set of tax data and started anew… nothing seems to make a difference.  The calculation is consistently off by the same number.   Perhaps this is happening because I did not make much profit from my business this year?  Or because I have to repay some of the Premium Tax Credit?  Or maybe it’s because my 1095-A does not have the same amounts for each column in all twelve months?  My form does have the correct enrollment premiums in column A, the appropriate SLCSP in column B, and accurate premium tax credit advance payments in column C.  None of the amounts are 0 or blank.  The totals for column A minus column C match the amounts I paid my marketplace insurer in 2025.  But when I enter the data in TurboTax exactly as it appears, the total is off.   Obviously, this won’t count as a federal tax break if my medical expenses are less than 7.5% of my AGI, or if I take the standard deduction.  But the number that TurboTax calculates for those Marketplace plan premiums is carried forward to the Missouri adjustment for Qualified Health Insurance Premiums, and there again, it’s a few hundred dollars off.  That number cannot be corrected or deleted.   Is this a known issue, and is there some workaround to correct it, or am I just going to have to settle for an imperfect filing?
