State of Michigan wants me to indicate if funds came from a 457B plan. Recently did an conversion to ROTH from what is now an IRA but was initially set up in a 457B. Upon retirement my 457B was rolled into IRA accounts. I am wondering if classification is based on current IRA designation or 457B classification due to the fact that the funds were accumulated initially under that 457B plan? Makes a big difference on how the funds are taxed. Even if I class it as a conversion, if the 457 box is checked it changes the full amount to taxable.
