I owned some EROC last year and received some dividend in my individual account. But my broker TDameritrade did not send me K-1. Along with my other my transanction descriptions there is one page called "partnership distributions".
Is this normal?
The partnership (not your broker) will issue the K-1 sometime in March.
Yes, the 1099 is correct to list it as partnership distributions - you need to wait for the K-1 for the actual information to declare on your tax return.
Sounds like you have quite a bit of homework to do if you are not planning to use a tax accountant.
