Yes

Where is HRA reimbursement entered in pro series to reduce s/e health ins. deduction?

Thats a good question   @TaxGuyBill is probably a good person to ask.   

I dont think it will let you just enter a negative amount in the SEHI box of the Sch C to reduce the insurance payments, will it?

pro series will not allow me to enter a negative number to reduce s/e health ins. deduction.

1095A col. A is $27,000 col. B & C are blank. HRA reimbursement by Ford (client is retired)

is $15,000. Program has $27,000 flowing to sch 1 health ins. deduction

Just enter the SE health insurance net of the reimbursed amount.

I would have to override, the s/e health ins. deduction flows from 1095A col A

to Schedule 1 line 17

I'm no help then. I don't use ProSeries.

If there is no Premium Tax Credit, just un-link the 1095-A from Schedule C.  Then enter the proper amount for SEHI in the 'regular' spot (if Schedule C, the entry spot on the Schedule C worksheet for it).

Thanks
