You don’t calculate a number for 2a. It comes from a 1099 Div box 12. If you don’t have any you can leave it blank. Is it for state?
For state tax exempt dividends……
There should be extra pages with your 1099 from the broker or fund listing them. Or you need to get the statements online from the company.
Some brokers are not including the backup detail sheets and tables now and you have to go online to get them. Like I have Vanguard and I'm in California.
