Investors & landlords

This is a stock I've had since 1987.  No Stock split has happened. Have no idea about the agents as I bought this initially on my own. I have every statement from 1987 until 2024. This weekend I spent hours going through my statements and figuring out average prices for the stocks that I've purchased in every year and made a spreadsheet. Just having a hard time figuring out and entering the Cost Basis in Turbo Tax, because entering various Cost Basis numbers change my refund totals by substantial amounts.

 

If my December 2024 Statement lists my cost basis at $7741, isn't that the number I use?

 

Sorry for the confusion, never have had to do this in all my years of using Turbo Tax.

 

Thanks again...
