Converting a Roth IRA back to a Traditional IRA (within the same tax year)

Does anyone know if this is possible?

 

After entering the amount converted from a Traditional IRA to a Roth IRA, the Premium Tax Credit (PTC) went away.  It now appears that I owe not only the tax on the converted amount (from traditional to Roth) I now need to repay the PTC.

 

The only way I see to avoid having to repay the PTC is to dissolve the Roth conversion.

 

Anyone have any knowledge of this tax situation?
