How do I categorize an all inclusive business conference?

Hello,

Im self employed and last year (before coronavirus) I travelled to increase my education and make myself more marketable in my profession. One part of my business trip was all inclusive and I’m not sure how to categorize it when filing my taxes. I paid one lump sum and that coved lodging, breakfast, dinner, educational lectures, and even some travel for relevant off site events. Do I have to break up the lump sum I paid to the best of my ability if they can’t provide me with an itemized breakdown of expenses?
