Received K1 after filing my taxes

[bpete2000]

I filed my taxes on March 9th and today I received a K1.  My brokerage account listed the investment in the 1099 so I thought the investment was included.  But the K1 is more detailed and includes 18-20 items listed. (Various incomes and losses and distributions, etc.)  I assume I need to file an amended return.  My return has been accepted and is still being processed.  Should amend it today or should I wait until the return has been processed?

You should wait until the tax return has been accepted and processed and a refund received (if there is one.)

If you used TurboTax Online, log in to your account and select Amend a return that was filed and accepted.

If you used the CD/download product, sign back into your return and select Amend a filed return.
