Need to Enter in Cost Basis but Popup Window is Too Small

Hi - I have recurring issues year to year where my imported financial data for stock sales is often missing data and during the review it asks me to add it but I can barely read what transaction it is asking about because the popup window it appears in is so very small. I would recommend  instead jumping people to the form directly where they can edit in the full screen and see overall what is missing or needed. But for now can you help guide me to where I can jump to the form to enter all of the missing cost basis data because I need to research each transaction?  Thank you!
