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
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).

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).
