Maybe it is appropriate to amend your return because Form K-1 of your MLP stock is available if it is CLMT. I think IRS will not go after you if you have paid more than what you owed. But, if it is less than what you owe, may be they will audit you. Once they start auditing you, it will audit you three to five in a row. I had real estate deductions, and boy, every deduction they question it and disallowed. Well, I had my share of experience with them, and I promised myself not to mess with them anymore.
Am very surprised to see #1 of my K-1 is +$1,640. Have 1000 unit only, meaning it is $1.64 per unit. For whole year, LINE is reporting a loss of $1.40 per unit. Out of my 16 MLPs , this one I cannot understand the accounting of my K-1 form. Am I screwed here?
arbtrdr, I know you are right that cost basis of old WPZ should move to new WPZ. My account at Scottrade didn't move. Value of the cost basis is less than the original. To me, this is a loss and I don't know how to report in my income tax.
