“My question is, can I write off that donation from my personal income?”----> You need to donate to a qualified charity.Tax law allows a deduction for charitable donations if you can itemize deductions on Sch A of 1040, if you do NOT itemize your deductions on Sch A of 1040, then you can NOT deduct your donations on your return. So, you ned to keep ongoing records of cash and noncash charitable contributions made throughout the year if there is a possibility that you can itemize.You need to use canceled checks, receipts or written records for cash or noncash donations of less than $250 in one day. You need an acknowledgement letter from the charity for donations of $250 or more and a written appraisal for noncash donations worth more than $5,000.

“ The receipt is made out to me, not the now defunct LLC. And if I can, is there a limit to how much I can write off, either based on a specific dollar amount or a percentage of my overall income?”--->Your donations to a charity reduced your taxable income, NOT your AGI as long as you itemize them on Sch A of 1040 and reduce your tax liability on 1040. However, the amount of some of those deductions is limited in order to keep them from being abused. These caps may be a fixed amount or a percentage of your income depending on the deduction. Your charitable contributions can total no more than 50 percent of your AGI, depending on the type of organizations to which the donations are made. The 50 percent limit applies to churches, educational associations, hospitals and public charities. Donations to all other IRS-approved organizations such as fraternal groups, veterans' organizations and private non-operating foundations foundations that provide financial support to charities have a 30-percent limit unless the donation is capital property, then the limit is 20 percent of your AGI. If there is a question about whether you can deduct donations to specific organization and how much, you should contact the IRS office or the charity. Excess contributions that are NOT deductible this year can be carried over for the next five years.
