Thank you for your response.
I elected to print the returns a few hours ago, and it doesn't appear I can go back and edit... nor do I have anymore energy to dedicate to this year's return. It's worth the $5 to mail the return to avoid any more frustration with this K-1 that has such an immaterial impact on my tax liability or refund.
I saw you helping folks with the same issue on the message board, and appreciate your help! I wouldn't be surprised if I made an entry mistake, although I have recorded this type of K-1 in the past, without any issues.
It was extremely frustrating not being able to find a customer support phone number, and being repeatedly advised to purchase the Tax Pro package by the chat-bot.
