Capital gains on dry stack...real estate 1099s & purchase of condo in other state

Hi....I sold a dry stack that housed a boat. Where do I put the 1099s and how do i determine my capital gains? Can I add to my purchase price the cost of the maintenance fees to maintain the stack for the time I owned it to cut down on the capital gains?

Next question. I own a house, I bought a condo in another state, but did not close to live there 6 months out of the year. Next year I will use the condo as my primary. I assume since I owned it less than 6 months out of the year the house has to be my primary this year? On that same topic do my bank statements need that address on them for 2024 since that will be my primary for tax purposes?

Thanks
