Retirement tax questions

Thank you.  Are you able to provide specific examples of what to enter as far as basis etc?  For example, I converted $1000 directly from traditional Ira to Roth IRA the very same day it was in my account, not incurring any gains.  Would $1000 be my basis?  Also, does it make a difference if I contributed after tax dollars to the traditional IRA before converting?  Thank you
