If I contributed to Roth TSP should I say yes I could contributed to Roth IRA on my taxes?

NO

Your entry only goes in where you enter your W-2 form.

And...a TSP is not an IRA....the IRA/Roth IRA contributions entry area is only for actual IRA's.

No, when your IRA contributions are made through your employer, you don't enter them in as IRA or Roth contributions.

All of the information about your employment based retirement plans is on your W-2 form and doesn't need to be entered again.

Only IRA and Roth contributions made on your own are reported by you on your tax return.
