I was able to find information Computershare has online for the Walmart ESPP, it says that the cost basis on the 1099B is for ALL Walmart ESPP shares I acquired through Computershare. That being the case, the cost basis would include both the shares purchased through payroll deductions and the shares that were bought with the company match. Therefore, I think I can accept the purchase basis as reported by Computershare and there will be nothing I need to add or adjust.
Thank you for responding and for your help.
