Deductions & credits

Rather than use the tool, shouldn’t I just fill in the rest of column B with similar amount that showed later in the year ($357.83)? Cause when I used the tax tool it came out to around 352 or something close to that and it clearly said “these are not the amounts you paid.”

 

It goes without saying the blanks for column C should stay blank as I didnt use the credit for those months, right? But the page will likely prevent me from continuing unless all the boxes have something in there (although I think I found a work around to that). I did recall seeing a older post that had a similar issue, and the tax expert suggested that they enter 0.01 in place of the blank, that way the system just rounds them down. Does that make sense?
