Missing winter sea-ice signals changes in Antarctica that could be “absolute disaster for the world”, scientists say.

No, I don’t just mean Thwaites. If the ice also runs off onto the mainland behind it, the sea level will rise by 60 meters. Thwaits is currently holding it back like a cork.
As covered by my quote, the neighboring mainland glaciers melting would raise water levels by 3 more meters (3.6m total). You’re still off by a factor of 20x
I got my information from this article: https://www.tagesanzeiger.ch/dieser-gletscher-determin-die-zukunft-der-menschheit-496385214213 It is Swiss, very long but well worth reading. Maybe you can find a way to translate it for yourself. It also says that the melting leads to a rise of 60cm in the short term, but to 60 meters in the long term (1000 years).
Per your own source: 60 meters is for the whole Antarctica. Thwaites and and the west Antarctica (which is the part “protected” by Thwaites) is 3.5 meters over a few hundred years (up to 1.000 years).
