<prompt>  Human: When Im withdrawing money from my retirement accounts, will I need to prove to the IRS that everything was done properly when contributing, going all the way back to when the money was first invested?For example, will I need to show when money in my Roth was first contributed, to ensure Im following the 5 year rule? Will I need to ensure the money I withdraw from my 401k was never over-contributed?It seems like this sort of thing would be really hard to track across a lifetime of rollovers and such...
