I'm using Quicken for Windows, version R55.26
I have just started using Quicken to help manage my brokerage account at Schwab. When I set things up I only received 90 days of activity from Schwab, so a vast majority of my tax lot information is missing. I know I can add this manually but that would be a huge job for 60 securities with many years of transaction history. I do have this data in an excel spreadsheet.
My question…is there any way I can utilize my Excel data and import it into Quicken? For example, can I create my own QXF file somehow to import into Quicken?
