There's nothing to *correct* as that's what happens when income spikes. 

The only options:

IRA, or HSA or SEP (if self-employed) to reduce income below the 401%.  OR, look at MFS - it sometimes can help.

You also should look at the treatment/taxation of the SS benefits received for prior years.  It may not help with the 1095-A situation.  You basically look at the prior years to see how much would have been taxable in prior years IF received in that year then adjust the taxable amount of the SS for the current year.
