Retirement tax questions

I'm actually doing this right now great instructions went right to it.  I don't see any way to input my cost basis.  I realize this will be taxed as income and I have my cost basis ready to be input if need be.  I have all 3 totals here:  Swiss Life annuity payment, my original cost basis from Swiss Life one time initial funding certificate and of course the taxable gain(to be taxed at income rate)

 

I see the entry description for 'total miscellaneous taxable income' and I'm assuming all I need to do is input the amount that is to be taxed, not the full Swiss Life annuity payment.

 

Thank you again for your knowledge and patience with me
