@fanfare For disability retirement purposes that is incorrect. In that case "minimum retirement age" is set by your retirement plan; it is the earliest age at which you could take retirement if NOT for your disability. This determines whether your disability retirement is reported as wages (100% taxable with no basis exclusion, eligible for EITC) or pension / annuity income (basis exclusion available if you made post-tax contributions to the plan, NOT eligible for EITC). Age 59-1/2 is only to determine if the 10% penalty for early payments MAY apply; there is likely an exception if you're over minimum retirement age but under 59-1/2.
I believe I will be running into this issue myself this tax year, as I became eligible to take early retirement under my former employer's plan. Alas, I'm using the IRS Free File version of TurboTax and the help question on what happens if you hit that age this year is missing (as it commonly is the IRS Free File version) so I'll be looking out for a more complete answer.
