Just this year, I received a K-1 for an investment in West Virginia. They withheld West Virginia state taxes from my distribution. When I am filling out my WV state tax, it keeps saying I owe the full 6.5% and will not let me enter the tax i have previo

Is the K-1 from a partnership?

Yes

If you enter all the information from the K-1, the taxes withheld will automatically flow to the state return.  There is no need to make a separate entry elsewhere for the WV withholding.

You didn't say whether the K-1 was from a partnership or an S-Corp.  The steps are the same, but the box numbers vary:

• In a K-1 from a partnership state withholding is reported in Box 13, Code W
• In a K-1 from an S-Corp, state withholding is reported in Box 12, Code S

To make the entry for state taxes withheld, follow these steps:

1. When in the K-1 interview, you will see the screen, Enter Box 13 Info.
2. Select W from the list and enter the amount.
3. On the next screen, Enter Code W Detail, mark the box Taxes and State Income Tax Withheld
4. In the section below the grey line select the State Name from the list and enter the amount listed in Box 13 Code W.

This figure will automatically flow to your state (WV) return.
