I submitted my deductibles to my company for nenmatsuchosei. What to do when filing kakuteishinkoku

Hello,
maybe a stupid question but here goes:

My company did the year end tax adjustment and I submitted my statement for ideco so it should be taken into account with my last salary already.

I also have to file the kakuteishinkoku because I used a lot of furusato nozei. Since my company already took into account my ideco payments, does it mean I only need to fill in the numbers from my tax withholding slip issued by the company and don't need to mention it again on the tax return? At least that is my guess as otherwise it might end up getting deducted twice which wouldn't be right.

Thanks

On your nenmatsu chosei summary from your company there should be a small number in brackets near the top left. This is your ideco total contributions for the year from the ideco paper you submitted to them, and the same number can also be entered in the during the kakutei shinkoku process (assuming you're doing it through etax). No further evidence or paperwork is required. I had the same concern last year but was surprised how easy it was.
