First of all estimated payments are optional to pay. They don't get sent with your return and the IRS won't be expecting them. You can ignore them.
Your tax return had $146 tax due after the extension payment? Or what do you mean you paid more than was due? How and why did you pay more? Did the $1,414 extension payment show up on schedule 3 line 10 which goes to 1040 line 31. The extension amount was not the final tax due amount.
