How can I insert rows on a spreadsheet?

I’m on windows 10 typing a spreadsheet. I need to insert several rows within the spreadsheet. When I try, a notice pops up stating, “FILLED CELLS CANNOT BE SHIFTED BEYOND THE SHEET”.

How do I solve this problem?

You have data in the row 1048576. Just delete intermediate empty rows, then add the new rows where do you need.
