Pretty sure p=1013.

Since 2027 is prime, the multiplicative group of integers modulo 2027 has order 2026, which has prime factorization 2*1013. If such a p exists, this means the cyclic subgroup generated by the element 2024^p must divide 2026, and so p must be either 2 or 1013. We can check that 2 doesn't work: 2024^2 - 2023^2 = 2024+2023 = 4047, which is not a multiple of 2027. Thus if p exists it must be 1013.

Not sure how I'd verify this p by hand but WolframAlpha confirms it.
