Man, the Social Security laws are written to screw you if

14. The problem seems to be that your sister's trust required you to cash in her IRA.

So you got a huge amount of money all at once.

While normally the estate pays all taxes before money is distributed, this is somewhat different, a cashing in of an IRA. The taxes you subsequently owed were because of your increased income, yours, not anything to do with the estate.

I know, it sucks to have to pay the extra Medicare amount. That happened to me my first year on Medicare, because of selling some investments of my own.

You might want to try appealing anyway.

One consolation is that you should still have over $30,000 from that IRA after the taxes and even after next year's higher charge on Medicare. Which is a tidy sum of money that you can enjoy.
