Retirement tax questions

Hi! Box 2a shows 0.00.

When I was working with Schwab they took the money out of the IRA and put it into the Roth. I believe I made the contribution in calendar year 2015 for 2016. The reason is I mistakenly thought I could contribute to both a traditional and Roth IRA but when I realized the contribution limits I asked them to remove the contribution  from my traditional and put it in my Roth.
