Long-term care insurance premiums

Taxpayer did not itemize deductions in 2023 and for many years previous. She PAID long-term care insurance premiums during 2023 (before the 2024 tax year), covering both the quarter ending January 31, 2024 and for the quarter beginning February 1, 2024.

 

She also paid a premium, during 2024, for the quarter beginning May 1, 2024. So, that makes three different payments covering the period 1/1/2024 through 7/31/2024, only one of which was paid during 2024.

 

If taxpayer itemizes deductions, which of these payments can be itemized as medical expenses for 2024?
