I returned your work but I want to know if I need to prepare myself to pay in on that. I can’t seem to find a clear answer
First---what year do you mean when you say "last year?" Are you referring to 2023? Or 2024?
What do you mean by "I returned your work....." ?
We need more information----you have not mentioned what tax documents you received (or will be receiving) for the disability payments. Are you receiving Social Security disability benefits--or some other kind of disability benefits?
You also have not mentioned what other income---if any---you received, nor do we know your filing status, whether you have dependents, etc. etc. etc.
Disability Income

In general:
If the short and long term disability is provided to you by your employer, and you either pay no premiums or your share of the premiums are deducted pre-tax, then the income is taxable. It should have been subject to regular withholding for income tax and social security and medicare tax, and it will either be included on your employer's W-2, or on a W-2 from the disability insurance company.
If you bought a private policy and paid with after-tax dollars (did not take a tax deduction for the premiums) then the income is not taxable.
