It looks like you have some additional capital gains transactions that imported with the dividends. The 1099-DIV information looks right with the $847 of ordinary dividends being included in income. The qualified dividends will be tax at the capital gains rate and are included with the capital gains tax calculation. The amount on line 7 is from the 1099-B form that imported with the 1099-DIV. These are probably stock or mutual fund sales transactions for the year that generated a capital gain. The capital gains dividends from the 1099-Div would be added to the capital gains generated from the 1099-B to equal the amount on line 7. I would recommend reviewing the hard copy of your 2020 Ameriprise combined 1099. You should should see a section for 1099-B Capital Gains transactions.
Note on Capital Gains, if the gains are short-term (less than a year holding period) the gains are taxed as ordinary income at your marginal rate. If the gains are long-term (more than a year holding period) they are taxed a the Long Term capital gains rate, which is 0-15%. Since your tax jumped, I am guessing the gains realized in 2020 are probably short-term but you will need to review your 1099-B information from Ameriprise.
