TurboTax will automatically calculate the amount that needs to be present on line 1 of Form 8880 based on your entries elsewhere in TurboTax of your Roth IRA contributions and distributions as DaveF1006 described. You do not enter anything yourself on line 1. If your distribution from the Roth IRA was an ordinary distribution (code J, T or Q but no code 8, P, N or R) the result will be $6,000 on line 1 and $1,500 on line 4
