I'm receiving social security, CSA retirement & a TSP annuity. i have been told that each of these income's are taxed @ a different rate, but i don't know the details. when i contacted each agency they said they could not give tax advice. i'm using turbo tax home & buisness bought from costco

I suggest that you (and others) use the IRS Withholding Calculator, available here https://www.irs.gov/individuals/irs-withholding-calculator

Read and follow the instructions.  Then follow-up with your income providers to ensure enough taxes are withheld.
