<human>: Can you give me a shortened version of the text?

I apologize in advance if this is a dumb question.  I know next to nothing about taxes and IRAs.

I filed my taxes two days ago, and just today I received a 1099-R from a previous job.  Given their track record, I'm not surprised it was mailed so late but I was not at all expecting this document which is why I had already filed my taxes.  When I quit the job, I received a payout of my 401k. This was sent to my bank and put into an IRA.  Shortly thereafter, I met with a financial advisor and put that into an appropriate mutual fund. I was told at the time that I would not be taxed on this as I was not withdrawing the funds for my personal use and had put them into the correct accounts to avoid that.  

Was I given incorrect information? I'm assuming I will need to file an amended return to include this amount.  Is there anything I will need to file in addition to that to demonstrate the money was invested into a mutual fund if, in fact, I do not have to pay taxes on it? I haven't received anything from my bank regarding it.
<bot>: Didn't include 401k pay out on taxes.  Financial advisor told me I didn't need to pay taxes on it.  What's true, and what's my next step?
