The national organization of AAUW is primarily a tax-exempt organization under IRC 501(c)(3).  A small part of the organization is a social welfare organization that engages in lobbying.  Therefore, your total national AAUW dues payment of $67 is allocated between the two entities, with $64 tax deductible and $3 not eligible for a charitable tax deduction. Dues paid to AAUW-Illinois ($10) are not tax deductible as charitable contributions. However, your $19 dues paid to AAUW Wheaton-Glen Ellyn Branch, NFP are 100% tax deductible.  In total, $83 is tax deductible (i.e., $64 to national plus $19 to the branch). The rest of your $96 dues payment (i.e., $13) is not tax deductible.

Example:  On April 1, 2022, you pay your total dues of $96 for the AAUW fiscal year of July 1, 2022 to June 30, 2023.  Of your total payment, $83 is tax deductible for federal income tax purposes as a contribution to charitable organizations. This breaks down to $64 to the national AAUW organization and $19 to AAUW Wheaton-Glen Ellyn Branch, NFP.  You are a calendar year tax filer.  Therefore, you may include $83 among your charitable tax deductions for calendar year 2022.

Your cancelled check is your receipt.  In some limited situations, the remainder of your dues may be deductible as ordinary and necessary business expenses if you are employed.  If you think this may apply to you, please consult your tax advisor.
