Stock owned as tenants by entirety after spouse dies

[Raeka]

I'm completing or trying to complete the worksheet for shares in our S Corp's stock. We owned stock as Joint tenants by entirety during which time we both owned 100 % of stock. Our CPA for years reported it as 50/50 ownership which wasn't legally accurate and later changed the way he did it after he learned he had treated it wrong. But my spouse passed in Nov. and now they are doubling the amount of shares on the worksheet if I put we both owned all the shares. Am I supposed to split it in the tax return?

Since your spouse passed in November, she should have a final K-1 with zero shares and you have 100%.
