Struct Schedule3Map 

pub struct Schedule3Map {
    pub form: String,
    pub year: i32,
    pub identity: IdentityCells,
    pub line1: MoneyCell,
    pub line8: MoneyCell,
    pub line10: MoneyCell,
    pub line11: MoneyCell,
    pub line15: MoneyCell,
}

The Schedule 3 (Additional Credits and Payments) field map for one tax year.

Only the foreign tax credit (L1) and the §6413(c) excess-Social-Security credit (L11) are mapped. Every other Part I credit is a §3.4 conservative omission and stays BLANK.

Fields

form: String

"f1040s3".

year: i32

Tax year.

identity: IdentityCells

The name + SSN header cells (P6.2). REQUIRED: a full-return schedule that does not name its taxpayer is not a filable form, so a map lacking [identity] fails at deserialization.

line1: MoneyCell

L1 — foreign tax credit, AMOUNT column.

line8: MoneyCell

L8 — total nonrefundable credits → 1040 L20, AMOUNT column.

line10: MoneyCell

L10 — “Amount paid with request for extension to file”, AMOUNT column. ★ Its absence made the filed return demand a payment the filer had ALREADY made (Fable ARCH-P6.3a D1).

line11: MoneyCell

L11 — excess Social Security / tier-1 RRTA withheld, AMOUNT column.

line15: MoneyCell

L15 — total other payments → 1040 L31, AMOUNT column.
