multi-year tax strategy and planning for transition to retirement, including IRMAA cliff thresholds, potential Roth ITA conversion amounts for individual tax situations, etc

Does Turbotax support multi-year tax strategy and planning for transition to retirement, including IRMAA cliff thresholds, potential Roth ITA conversion amounts for individual tax situations, etc... does Turbotax have on-line (or downloadable) tax planning forms or spreadsheets to help guide Roth IRA conversion plans for multi-year execution to fill up tax brackets under the new tax law?
