can you add anything?
A little bit.
So my partnership extension was filed by March 15, and I am in NY, not a community property state........ we both need to file schedule C's
You need to forget about SCH C. You live in NY, so that's not an option for you.
After I file Form 1065, and generate K-1'S, which will have my unreimbursed miles,
No. The K-1 would include money paid to you for "REIMBURSED" miles - not "UN"reimbursed miles. That money would be taxable income too. Remember, a partnership isn't just a pass-through entity, it's also a disregarded entity.
I am still left with medical to write off
Your medical expenses are an itemized deduction on SCH A, subject to a number of limitations/requirements before they will have any impact on your personal 1040 tax return. If the partnership did not have a qualified medical plan or medical insurance plan in place in 2019, then the bottom line is, medical expenses are a SCH A deduction on the personal 1040 return of each partner. (Filing MFS will *NOT* make things better either - it will make them worse.)
If the partnership (not the individual partners) provided health insurance to the partners, and the partnership (not the individual partners) was legally obligated to pay it on behalf of all the partners, then the amount paid by the partnership would be shown in box 13 of the K-1 with code "M". That amount in box 13 with code "M" would be transferred to the SCH A of the partner's 1040 tax return. So it's "still" a SCH A itemized deductions subject to the limits and requirements imposed on itemized deductions.
