It worked by following below mentioned steps. step1 is from help center of webull. step2 is from turbotax while filling the crypto currency. Hope it helps someone.
step1:
To upload your crypto tax document into TurboTax it must be downloaded as a CSV file. If there is an issue uploading the file to TurboTax, then the file may contain too many columns. The only required fields for the crypto tax statement is Symbol (column F), Acquisition Date (column Y), Disposition Date (column Z), Cost Basis (column AA), and Proceeds (column AB). If you remove the unnecessary columns from the CSV file and reupload the document to TurboTax it should upload successfully.
step2
1.Open your CSV file and find the headers at the top of each column.
2.Make sure your file has the following headers: Currency Name, Purchase Date, Cost Basis, Date Sold, Proceeds. (They don’t have to be in this order.)
3.Edit any header labels that don’t match.
4.Resave and upload your CSV file.
