Unfortunately, I cannot answer that directly as the amount deducted for Medicare depends on income in a prior year, 2017 for the 2019 Social Security payments. This is explained in, for example,
https://money.usnews.com/money/retirement/social-security/articles/how-social-security-and-medicare-...
The details appear in
https://www.cms.gov/newsroom/fact-sheets/2019-medicare-parts-b-premiums-and-deductibles
You almost surely received a letter in December 2018 telling what your Social Security income would be and what deductions would be made from it. You can compare it to the details given in the link above.
