You might have to delete the 1099R and re-enter it. The 8915E is available in TurboTax Online. It is not available yet for the Desktop products. The 8915-E will be used for penalty relief from early retirement plan distributions and include the option to spread the distribution income over 3 years. This may be a good option if the distribution is pushing you into a higher marginal tax bracket. You may end up paying less tax if you spread the distribution over the 3 years
