How do I amend my 2024 return to edit Lump-Sum Distributions?

Due to a TurboTax error, some customers did not pay the correct amount of tax on their lump-sum retirement distribution. TurboTax was rounding the distribution percentage when calculating the tax. As a result, taxpayers underpaid or overpaid their federal and, if applicable, California tax liability.


If we notified you, we recommend you submit an amended federal and, if applicable, state tax returns as soon as possible to avoid additional penalties and interest on the unpaid balance.
