This is my Second Year of filing FED and STATE return for a Traditional IRA (Pre-Tax) to ROTH IRA Conversion. NJ State has already taxed my Federal TSP contributions, however, NJ Division of Taxation requires filing taxes on TSP earnings

This is my Second Year of filing FED and STATE return for a Traditional IRA (Pre-Tax) to ROTH IRA Conversion. NJ State has already taxed my Federal TSP contributions, however, NJ Division of Taxation requires filing taxes on TSP earnings.  Therefore, a partial taxable amount is required (i.e. NOT a full conversion of the ROTH Conversion Amount).

The PROCESS of seamlessly transferring tax data  from the TurboTax FED forms in to the TurboTax STATE forms lacks clarity; i.e.  in other than patchy messages from "reddit users" etc.    Is there a more formal discussion about handling this TurboTax FED to NJ State form data transfer and any tips/cautions on the full process.   I know this is a big ask!  Any help , suggestions or link updates would be appreciated.
