Thank you so much for correcting what you had assumed.
I am glad that Lincoln was also willing to correct the situation so you could file your return.
Unfortunately, as far as whether disability or a sick pay claim is taxable or not depends on a lot of details...who paid the premiums for the short and long term disability is a big factor that can affect the box 1 amount, so if the issuer doesn't know how much should be in that box it is difficult for someone else to make that determination.
