I am also having a problem with line 10 on form 2210. I am annualizing (I checked box C in part II) and line 10 should carry over the amounts from line 27 on schedule 2210 AI. But there's a problem with column (a) on line 10 because it carries over the total in both columns (a) and (b) of line 27 on schedule 2210 AI, not just the amount in column (a). Columns (b), (c) and (d) on line 10 are carrying over the correct amounts from line 27.
